How are you? Guess what? We're moving houses again! I know! It's ridiculous right? I hate it. We have moved three times in two years. I just got to know my new school friends and suddenly it's time to leave again. Mum and Dad are packing up things upstairs right now. I should be helping, but the thought of putting all my stuff in boxes again makes me want to cry. It would be so much better if Dad had a normal job. I just want to stay in one place for a few years. I am going crazy with all this constant change.
